Dragons' Lock

Dragons' Lock by Red Tiger is a video slot with five reels and four rows featuring 40 fixed paylines. The game has a fantasy theme, with dragons, treasure chests, and keys as central elements; the atmosphere exudes adventure in a fiery cave. The main feature revolves around the “Dragon Chests” above the reels, three treasure chests with instant payout prizes when you have collected enough “Dragon Keys.” Keys only appear on reels 1, 3, and 5, and can sometimes be accompanied by a multiplier of x2, x3, x5, x10, or x20; if multiple keys with a multiplier open the same chest, the multipliers are added together.

At the start of the game, only the first chest is available; you need five Dragon Keys to unlock the second chest, and another five to open the third one. Once all three chests are unlocked, each key automatically opens the corresponding chest for a standard prize. The three chests contain different reward levels, ranging from relatively modest to high-end rewards up to 250× your bet.

Free Spins are activated by three Free Spins Scatters on reels 2, 3, and 4; you will receive ten free spins, and during this bonus round, the chance of Dragon Keys appearing is increased. The Free Spins can be re-triggered if you score three scatters again during the round. There is also a Feature Buy option: for a bet of 20× your stake, you are guaranteed at least one Dragon Key and all chests are active, and for 80× your stake, you buy the Free Spins bonus directly with all bonus mechanics enabled. The game also features Wild symbols that can replace all paying symbols to complete winning combinations.

You can play it for real money.
